Fix astream_events modifying output format unexpectedly
...
- (unrelated) use run_id passed in
- if using a graph as node in another graph ensure stream_mode for inner call is always values
- ensure langchain-core doesn't auto promote streamed dicts to addable dicts, which results in unexpected output (only) when calling astream_events

Rewrite Graph/StateGraph.compile()
...
- Each iteration of the graph is one single iteration in Pregel (ie. no more "{node}:edges" nodes)
- .update_state() now acts exactly as one of the nodes in the graph (which can be chosen), which makes human-in-the-loop scenarios where you want to override the actions of a specific node a lot easier to build
- Graph/StateGraph.compile() now delegate adding nodes/edges/etc to dedicated methods that operate on the Pregel object, which is 90% of the way towards dynamic graphs where nodes and edges can be added during execution
